Definitions

  • the present invention relates to a method for manufacturing a branching portion formed in various types of wire harnesses for automobile wiring, for example.
  • a longitudinal dimension of electric wires composing a branch line 1 is provided not as a minimum length to directly branch at a branching position P 1 from a trunk line 2 but as a length provided with a U-turn formed turning portion 3 .
  • tape winding is applied for uniting and protecting the branch line 1 and branch line 2 .
  • tape winding is applied from the terminal side of the branch line 1 , to which a connector 4 is connected, toward the branching position P 1 .
  • the tape 5 - 1 wound around the branching line 1 is wound up to a U-turn turning point P 2 of the U-turn turning portion 3 , namely, a branch-line-side unilateral portion 3 a of the turning portion 3 .
  • a tape 5 - 2 is wound from its one end.
  • the tape 5 - 2 is wound up to the U-turn turning point P 2 while uniting electric wires of the trunk line 2 and a branch-line-side unilateral portion 3 b of the turning portion 3 .
  • the tape 5 - 3 wound from the branching position P 1 to the U-turn turning point P 2 is wound up to the other end side of the trunk line 2 , whereby the trunk line 2 is wound with tape across the entire length.
  • the above-described prior art has a problem in that, since the turning portion 3 is formed, the electric wires composing the branch line 1 have a long length, causing an influence on the cost, etc. In addition, it has a problem in that, since the electric wires composing the branch line 1 are bent, this causes breaking of wires or an influence on durability. Furthermore, it has a problem in that an increase in the number of electric wires composing the branch line 1 makes it difficult to form the turning portion 3 . Still furthermore, the peripheral size of the branching position P 1 is increased and sometimes fails to satisfy its standard.
  • the present invention has been made in view of the circumstances as described above, and an object thereof is to provide a method for manufacturing a wire harness branching portion which is easy to manufacture to lower the price, in addition, which has no worry of wire breaking and is excellent in durability, and furthermore, which can sufficiently satisfy the standard size.
  • a method for manufacturing a wire harness branching portion described in the first aspect of the present invention made in order to solve the problems as described above is provided in that, manufacturing is carried out while including the steps of: from a trunk line of a wire harness, drawing out electric wires to be a branch line longer than a required length of the branch line; forming a branch line portion by applying tape winding to the drawn-out electric wires; making, as a trunk line accompanying part, a part from a base end to a branching position of the branch line portion accompany the trunk line and making, as a main branch line part, a part from the branching position to a front end of the branch line portion distant from the trunk line; and applying an protecting treatment by tape winding to the whole.
  • a method for manufacturing a wire harness branching portion described in the second aspect of the present invention is provided in that, manufacturing is carried out while including the steps of: separating, out of a plurality of trunk lines composing a wire harness, a first trunk line including protecting target electric wires from a second trunk line not including protecting target electric wires; from the first trunk line, drawing out electric wires to be a protecting target branch line longer than a required length of the branch line; forming a protecting target branch line portion by applying tape winding to the drawn-out electric wires; making, as a trunk line accompanying part, a part from a base end to a branching position of the protecting target branch line portion accompany the first trunk line and making, as a main branch line part, a part from the branching position to a front end of the protecting target branch line portion distant from the first branch line; from the second trunk line, drawing out electric wires to be a general branch line with a required length of the branch line to provide as a general branch line portion and making the general branch line portion distant from the second
  • a method for manufacturing a wire harness branching portion described in the third aspect of the present invention is provided in that, manufacturing is carried out while including the steps of: from at least two trunk lines composing a wire harness, and including protecting target electric wires, drawing out electric wires to be, separately, protecting target branch lines longer than a required length of the branch lines; forming protecting target branch line portions by respectively applying tape winding to the drawn-out electric wires; making, as trunk line accompanying parts, parts from each base end to each branching position of the protecting target branch line portions accompany the trunk lines, respectively, and making, as main branch line parts, parts from each branching position to each front end of the protecting target branch line portions distant from the trunk lines, respectively; while aligning the main branch line parts in position with each other, overlapping the trunk lines with each other; and applying an protecting treatment by tape winding to the whole.
  • manufacturing steps of shifting the drawing-out position of electric wires to be a branch line to a more upstream side than the branching position and protecting the section between the drawing-out position and branching position by tape winding are included. Namely, a manufacturing step of protecting, not only the section from the branching position to the front end of the branch line, but also the upstream side beyond the branching position by tape winding is included.
  • the present invention since it is unnecessary to lengthen the length of electric wires composing the branch line, and in addition, it is also unnecessary to provide a U-turn formed turning portion as in the prior art, productivity can be heightened to provide a wire harness branching portion at a low price. Furthermore, as described above, since it is unnecessary to provide a U-turn formed turning portion, occurrence of wire breaking can be prevented and durability can be improved. Still furthermore, an advantage is provided in that a compact wire harness branching portion can be manufactured. Therefore, the present invention has an effect in providing a method for manufacturing a wire harness branching portion which is easy to manufacture to lower the price, in addition, which has no worry of wire breaking and is excellent in durability, and furthermore, which can sufficiently satisfy the standard size.
